, specification df Leiters Plata# Be it known that I, HENRY S. Genoma citizen of the' United States, residing at the city and count-y o 'ffSan Francisco,-1State v of California, have invented certain newandusefullmprovements 'in Resilient Vespecification.

vhicle-Viheels, of which the following is a' rvMv invention relates to resilientv vehicle` wheels, and its object is to provide'ja wheel for motor vehicles possessing the salme r siliency and shock ahsorbingproperties as the air-filled tire.v The original cost, liability to puncture, limited load carrying properties, and the cost of maintenance makes the air-iilled tire undesirable and under some conditions impractical'. 'In my inven-- tion the above objectionable features are eliminated without the'loss of, resiliency or shock absorbingproperty. K e

The invention pertains to the kind ofvehicle wheels disclosed 'in my pendingapplication, resilient vehicleV wheels, filed July 29th 1912, Serial No. 712,194'. f

vMy invention may be equipped and used with any desired tread, such assolid rubber, wood, fibrouscompositionf'or metal.

My invention is illustrated inthe accompanying drawings, in.which:" i, .i

Figure 1, isa view in elevationof the wheel withv a broken section showing the assembly of the overlapping springs, and the manner in which they break joints at every point/.of` bearing. Thisview also shows the driving toggle, andthe buffer ring and face plate in elevation. Fig. 2, is aview in cross-section taken on the line X-Q Fig. 1.v Fig.

3, is an enlarged cross-section vof apart of the wheel taken on the line XX, Fig. 1, showing the channel rim with solid rubber tire, thev anchorage of the toggle drive,

and the face plate and the dust-proofpacking rings in place. This view also shows the buiferf rings in cross-section and a part of the rubber tire in plan. Fig. 4, is an enlarged view in cross-section Vof a partof the ,wheel taken on the line Y-Y, Fig. 3, showing the overlapping springs iny place, the toggle drive and the felly slot in which the lower member of the toggle drive isy anchored.

of any suitable type for mounting. the tread-iy 5. The backv plate vc, is rigidly secured to thechannel rim and becomes "integral there- Awith while theface plate 7, is detachable;

vThe outer edge ofthe Vface plate rests on a ledge 8, provided therefor on the inside 'of the lchannel rim. At the bottom of this ledge is a. packing groove 8, 4making a dust proof and water-tightfjoint. The ychannel rims, back, and face plate form aboX inwhich the felly 2, is Vslidably mounted. The

Vspra'ce between' the inside ofthe channel rim 4, and the shoe oft-he felly 3, forms the chamber in 'which the` Aoverlapping springs; 9,9,y are assembled as well as the toggle driving device 10.` The clearance yslot 11,

is provided to allowgreater play for the A device as well as to form a convenient an.v

chorage for the same. At or near the lower edge of thel back and face plates, 0n; the

`inside of each, are the packing grooves 12,

12. These grooves, are duplicated in the felly 2, at itsouter'edge; the metallic rim 3, forming one side ofthe slot. In the grooves referred to are placed the packing 1 i rings 13, 13. This Spacking is preferably of felthand serves to keep out dust andy wa- /tenfand to retain the lubricant,l forV the springs. 114;, 14', are the buifer rings rigidly securedl to therfelly 2. kThe spacing studs` 15,15, vare placed in any desired numberV and serve to Asecure the face plate as well as toform ananchorage for the upper member of the drivingtoggle 10.

The operation ofmy invention is asv follows -The overlapping springs vare assembled yin the chamber, formed by the vdiiference between the internal diameter ofthe channel rim and the peripheral diameter of the felly, in such a manner as to overlap and" break joints at every point of load contact.

This manner of assembling forms av multiple -leaf `spring of even thickness .icoy f around the entire wheel, acting as a unit. In f the arches of the spring the toggle drivingA p device is placed'giving perfect freedom to -v Y the action of thespring but rigidly resisting. the torque of power applied to the wheel Y i Y for driving. The chamber `is. 4then filled with a suitable lubricant'and the face plate';

securedin place. The wheel l is now ready for servlce, free from the annoying and eX- pensive faults of the ordinary pneumatic'.L

tire. The shape of theloverlapping springs,l i

and the manner in which they are mounted, distributes the load carried by the Wheel through the entire length of the spring. This gives the maximum of efficiency'in both resistance and resiliency. Should the springs break under load, the Wheel settles down in the channel until the side platesV ride on the buier rings. This enablesthe truck to deliver its load safely before the necessary repairs aremade. s

I do not Wish to be understood as confining myself to the precise construction shown herein, but Wish to avail myself of any 4modification that maypro-perly fall Within tric therewith, side plates forming a chamber, a multiple of overlapping springs interlaced, said springs forming an even means of resilient resistance bet-Weenthe channel rim and the felly, flexible connections securing the channel rim to said felly, assembled Within the arches of said springs and comprising inner and outer transverse rods,` two levers pivotally carried on the 'respective rods and having a toggle joint 'connection with each other, said outer rods having their ends permanently secured in said side plates, said inner' rods being secured Within side pockets, and a circumferential band nsecured to the o-uter periphery Aof the felly yprovided with slots registering With said pockets, substantially as described.

In testimony whereof, I afix my signaf ture in presence oftivo Witnesses.
